🚨UPDATE your @Apple products now!

We @citizenlab w/TAG's @maddiestone caught #predator spyware attacks against a prominent pro-democracy Egyptian politician after he announced presidential ambitions.

Apple rushed a patch.

It gets crazier 1/

citizenlab.ca/2023/09/predat…
Between May and September 2023, former Egyptian MP Ahmed Eltantawy was targeted with Cytrox’s Predator spyware via links sent on SMS and WhatsApp. The targeting took place after Eltantawy publicly stated his plans to run for President in the 2024 Egyptian elections. In August and September 2023, Eltantawy’s Vodafone Egypt mobile connection was persistently selected for targeting via network injection; when Eltantawy visited certain websites not using HTTPS, a device installed at the border of Vodafone Egypt’s network automatically redirected him to a malicious website to infect his phone wi...
2/ Ahmed Eltantawy got in touch with us @citizenlab, worried his devices were targeted in #Egypt.

He was right. His iPhone on @VodafoneEgypt was targeted for network injection.

As he browsed the net, the attackers were trying to slip a #Predator infection onto his device.

Image
Image
3/ It gets worse.

We attribute the spyware injection system to a @Sandvine Packet Logic product w/high confidence.

Sandvine has been accused in past of facilitating human rights abuses in the past.

Owned by NSO Group's former owner Francisco Partners.

4/ This kind of exploit delivery through injection DOES NOT require a target to click as our collaborator, the brilliant @maddiestone, points out in her post.

It's a seriously dangerous kind of attack & hard to protect against.

@maddiestone 5/ Apple moved quickly to fix the zero-day exploits @maddiestone & @billmarczak discovered.

We encourage everyone to immeidately update their apple products.

There is a piece of good security news buried in all this... Image
@maddiestone @billmarczak 6/ We believe & Apple's Security Engineering & Architecture Team confirms, Lockdown Mode would have blocked this attack!

We *strongly* encourage all Apple users that may be at risk because of who they are or what they do to enable Lockdown Mode!

@maddiestone @billmarczak 7/ Ahmed ElTantawy wasn't just targeted with network injection!

He was also targeted with #Predator spyware links in decoy messages sent as texts & over @WhatsApp.

One of the attacks masqueraded as communications from the International Federation for Human Rights @fidh_en Image
@maddiestone @billmarczak @WhatsApp @fidh_en 8/ This summer the 🇺🇸US hit developer & distributor of #Predator spyware (Cytrox & Intellexa) with blacklisting.

This latest abuse revelation affirms the determination that the spyware continues to fuel human rights abuses.

9/ Pulling back the lens from the tech side of this #Predator attack:

Mercenary spyware is autocrat fuel.

When you hack a pro-democracy presidential hopeful in an autocracy... you are doing dictatorship.

And spyware companies know exactly who they are selling to. Image
10/ Without brave victims like Ahmed Tantawy getting checked & coming forwards, these recent exploits would not have been found.

Billions of apple devices would still be vulnerable.

Including yours. Image

NEW: Ex exec at premier private cyber weapons contractor to US accused of selling eight trade secrets to buyer in Russia.

I think this = exploits.

Very bad: at minimum would give adversaries a blueprint for detecting the tip of the spear of US/Allied cyber ops..

Wild story 1/Image
Image
2/ A watch collection studded with fake rolexes...

...is allegedly part of Peter "doogie" Williams haul from selling the hacking labs' secrets.

documentcloud.org/documents/2619…Image
3/ While doogie's watch collection is a joke, the questions couldn't be more serious:

Were cyberweapons paid for by American taxpayers also turned against us?

Were service members, officials, or civilians at physical risk? When was this breach first suspected? Who knew what? When?Image

WARNING: seeing a lot of phishing against @Signal users.

Did you get a message like this?

Don't engage! It's an attempt to steal your account.

Your account is safe & chats are private, but you should use Signal's option to Report Spam & Block. 1/Image
2/ You can make the attackers life harder by clicking Report.

Background: Like any popular secure messaging app, Signal users sometimes get targeted by spam & phishing attempts.

Often, attackers guess large numbers of usernames / phone numbers & send out message requests...Image
3/ Take a minute to remind yourself how message requests & blocking work on @Signal.

A "damaging" leak of tools from a five eyes exploit developer?

Concerning. We need to know what's under this rug.

Big picture: "trusted, vetted" private sector players offensive cyber are not immune to losing control of tooling... with national security consequences 1/
2/ If true, a tooling leak at boutique firm Trenchant wouldn't be the first time that exploits from commercial offensive vendors wind up... in the wrong place.

Many questions.

In the meantime. Remember when Russian APT29..was caught with exploits first used by NSO & Intellexa? Image
Image
3/ There will always be a push for states to turn towards the private sector to meet offensive needs.

It's appealing. For some, it's very lucrative.

But in practice it brings unavoidable counterintelligence & national security downside risk that shouldn't be downplayed.

NOW: US court permanently bans Pegasus spyware maker from hacking WhatsApp.

NSO Group can't help their customers hack @WhatsApp, etc ether. Must delete exploits...

Bad news for NSO. Huge competitive disadvantage for the notorious company.

Big additional win for WhatsApp 1 /Image
Image
Image
Image
2/ Although the massive punitive damages jury award against NSO Group ($167m) got reduced by the court, as is expected in cases where it is so large (to 9x compensatory damages)...

This is likely cold comfort to NSO since I think the injunction is going to have a huge impact on the value of NSO's spyware product.

Comes as NSO Group has been making noises about getting acquired by a US investor & some unnamed backers...Image
Image
3/ NSO also emerges from the @WhatsApp v NSO case with just an absolute TON of their business splashed all over the court records..

E.g. check out the filings from Sept 15th 2025: courtlistener.com/docket/1639534…

WOW: @Apple donating a thousand new #iPhone17 s to civil society at-risk from mercenary spyware.

Good. This will help get Apple's most secure devices to where they need to be..

Truth is: those at the greatest risk from spyware are often least able to afford more secure phones 1/Image
2/ Memory Integrity Enforcement = big deal Radically hardens iPhones from common attack vectors.

So it was a bittersweet to see this announcement and think "yeah it's going to be a long time before highest risk ppl can get them."..
3/ You're reading this on a device that is probably more secure thanks to the vigilance of an activist somewhere...

Seems @Apple recognizes this & also knows how much of a game changer getting their most secure devices into the hands of civil society could be.

NEW: fresh trouble for mercenary spyware companies like NSO Group.

@Apple launching substantial bounties on the zero-click exploits that feed the supply chain behind products like Pegasus & Paragon's Graphite.

With bonuses, exploit developers can hit $5 million payouts. 1/Image
Image
2/ Apple is introducing Target Flags which speeds the process of getting exploits found & submitters rewarded.

This faster tempo is also a strike against the mercenary spyware ecosystem.

And the expanded categories also hit more widely against commercial surveillance vendors. Image
3/ If I contemplating investing in spyware companies I'd want to carefully evaluate whether their exploit pipeline can match what @apple just threw down.
